Function

GObjecttype_add_class_cache_func

Declaration

void
g_type_add_class_cache_func (
  gpointer cache_data,
  GTypeClassCacheFunc cache_func
)

Description

Adds a GTypeClassCacheFunc to be called before the reference count of a class goes from one to zero. This can be used to prevent premature class destruction. All installed GTypeClassCacheFunc functions will be chained until one of them returns TRUE. The functions have to check the class id passed in to figure whether they actually want to cache the class of this type, since all classes are routed through the same GTypeClassCacheFunc chain.

This function is not directly available to language bindings.

Parameters

cache_data

Type: gpointer

Data to be passed to cache_func.

The argument can be NULL.

The data is owned by the caller of the function.

cache_func

Type: GTypeClassCacheFunc

A GTypeClassCacheFunc.
